156120SS82500P

Overview

The Würth Elektronik 156120SS82500P is a single-color surface-mount LED from the WL-SMRW series, emitting red light at a peak wavelength of 630 nm. Housed in a 3216 (1206) metric package with dimensions of 3.2 mm x 1.6 mm x 1.85 mm, it features a clear dome lens and a 20-degree viewing angle. The component operates with a forward voltage of 2.4 V and a maximum forward current of 40 mA, delivering an optical intensity of 900 mcd. It is rated for a power dissipation of 48 mW and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Features a water-clear dome-shaped lens designed to optimize light emission directionality.
• Constructed for surface-mount technology (SMT) assembly on printed circuit boards.
• Complies with RoHS standards for restricted hazardous substances.

Applications

• General-purpose electronic status indicators
• Panel-mounted visual signaling devices
• Consumer appliance control interfaces

Procurement Notes

Verify the specific suffix 'P' against the manufacturer's official documentation to confirm packaging configuration, as ordering codes may denote reel or cut-tape variations. Ensure compatibility with standard SMT reflow profiles and check moisture sensitivity levels prior to storage. Confirm that the 40 mA maximum rating aligns with the target circuit design constraints.

Selection Notes

Select this component when a compact 3216 footprint is required for high-intensity red indication. The 20-degree beam angle suits applications needing focused visibility rather than wide-area diffusion. Consider the 2.4 V forward voltage drop for appropriate current-limiting resistor calculations in low-voltage logic circuits.

Part Context

This part belongs to the Würth Elektronik WL-SMRW series, which provides standardized surface-mount LEDs for industrial and consumer electronics. The series offers various colors and intensities within consistent mechanical footprints, facilitating design flexibility and supply chain standardization across different product lines.

Replacement Considerations

Cross-reference with other 3216 red LEDs such as the 156120SS82500 variant if packaging differences exist. Verify electrical parameters like forward voltage and luminous intensity match the original design requirements before substitution.
